You're a new lump (it's good thing, trust me)

A little leaven leavens the whole lump. (Galatians 5:9, ESV)

What a funny little phrase! Yeast has way of spreading and once the yeast gets into the dough, it is nigh impossible to get it out again. Only God can get the yeast out of the dough once its in...and he has! Yeast is sin. You are the lump (nothing personal, just quoting). Paul writes in 1 Corinthians, "Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth (1 Corinthians 5:7–8, ESV)" You're a new lump. Rejoice!
